CATULINUS (CATHOLINUS), JANUARIUS, FLORENTIUS, JULIA and JUSTA (Saints) Martyrs (July 15) (Date unknown) Carthaginian Martyrs. Of Saint Catulinus (a deacon) we have a Panegyric in one of the Sermons of Saint Augustine; but beyond the fact that their bodies were enshrined in the famous Basilica of Fausta at Carthage, we have no particulars concerning him or his fellow-sufferers.
